This invention relates to a guard structure adapted to be placed alongpublic highways, grades and bridges, for the purpose of minimizingautomobile accidents, and injury. to persons and property.

, An object of the invention is the provision of an improved type ofdevice, a plurality of which are respectively attached to spaced postsor standards along the side of the highway, and designed and adapted tohold a cable or like element up from'the highway and away from the lineof posts lengthwise of the highway, to present a continuous smoothcontact surface which may be encountered by automobiles or othervehicles traveling on the highway, and be prevented from leaving thehighway, and also to prevent serious damage to automobiles or othervehicles coming'in contact therewith while traveling on the highway in adirection par alleling the cable;

Another object of the invention is to provide a device of the indicatedcharacter which M facilitates stringing of'the cable, which securelyholds the cable in place, andwhich is of simplified and durableconstruction.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read inconnection with the accompanying drawing, in which- Figure ,1 is a sideview of the upper end of a post with a cable holding device of thepresent invention applied thereto.

Fig. 2 is a plan view.

I .Fig. 3 is a central vertical sectional view. a Fig. 4: ma horlzontalsectlonal view takenv on the line 4-4 of Fig. 3. a

4 Fig. '5 is a view ofthe jaws of the device the cable.

In accordance with the present invention a plurality of spaced posts orstandards are arranged along the side of a public highway steep grades,and on bridges. Each post or standard will have attached thereto asimilar device adapted to cooperate with others to support a cable orlike element lengthwise 5 along the highway paralleling the same away ingripping engagement with a portion of at different locations, such assharp curves,

from the line of posts. Referring nowmore particularly to the drawing itwill be apparent that thereisshown the upperend of a post or standard10, which-may be :ofany suitable heightand cross sectional shape andsize,- and in the present instance is a wooden post round in "crosssection; The cable hold-- ing device attached to the post 10 consists ofan arm 11 having a part 12 which-conforms to the shape of the post and ajaw 13. The part ward thehighway. *The arm 11 has a recess '15Iin theunder-side thereof, ahole l6, and

.12 has holes which respectively receive a fasalso a bore 17 forpurposes to appear. A bolt.

18fis employed and has a jaw 19 at 'one end, and the opposite end isthreaded asat 20. The bolt 18 is of a-diameter to fit the bore 1'? inthearm 11, and is of a length to extend through'the upper end of the post10, the latter being provided with a transverse hole for that purpose.Thej aw 19 on the bolt 18 is 'receivable in the recess 15- which.conforms to the, shapeof'thejaw 19. It will be ap parent that'the aw19: is movable .orslid'able relatively to the jaw 13, and is adaptedtocooperate the-rewithtovgrip' a cable'or-likelelen1ent '21: ThejawsBand 19 aredesigned.

and constructed to gripffthe cable in sucha manner that acontinuoussmooth contact surface indicated at; 22 will bespre'sented. The jaw19 bybeingmovable relatively tothe j aw 13'. may be brought to-apositio-n'toenable a cable to be brought between both jaws to In orderto aid the 13 19 in holdfb'e gripped thereby, or to"release the cablewhen-necessaryorf-whenever theo'ccasio-n 7 ing the cable a wedge or key24 may be driven 7 between the jaws 13 and 19 and the'cable 21 r isshown most clearly in Figs. 1 and 3.

' In order to protect the upper endof the post 10 and to distributethestrain on thebolt 18 there is provided a cap 25 having depending lugs26 and 27 arranged diametrically opposite each other. The lug 26 isreceivable in the hole 16 in the arm 11, and the lug 27 Q 7 contactswith the side of the post 10 when the cap is in place on the top of thepost. The lugs 26 and 27 have holes respectively in alinement andreceive the bolt 18. The nut 23 is screwed up against the lug 27 andsecurely fastens the parts together.

' It is 'tobe understood that alte'rn aterelatively high and low postsor standards may be located along the side of the'highway, each post orstandard-having a devic'e oi thebharacter described, making it possibleto support two cables up from the highway atdifierent elevations, awayfrom-the line of theposts orstandards, and disposed lengthwise of orparallel to the highway. It is also to be under- Y stood that-asinglecabl'e may be supported in the manner described. .lVhere twocables-are used, one willbe dispose-d low enough to be below the hubsofthe automobilewheels, and

the other Well to the top of the wheels.

Where one cable is used it may be'arranged to come either below or abovethe hubs of the automobile wheels, preferably below the hubs.

I claim:

1. The combination with a post, of a cap arranged on the top of thepost, said cap having lugs arranged oppositeeach other-,'an arm rigidlysecuredto said post and projecting laterally therefrom, saidarmhavingajaw formed integral therewith, one of said lugs fitting into a hole inthe arm, and the otjh'er lug depending in co'ntactwith said post, a boltextending loosely through the post, arm and lugs and having slidingmovement rela tive thereto, a jawon' one end offsaid bolt,

the bolt being of a length to bring the aw thereon into a grippingrelationshipwith respect' to the otherj aw, and a nut in threadingengagement withsaidbolt'to hold-its aw in the gripping relation withrespect to the other aw.

2. A clampingdevice comprising-a cap havinglugsarranged OPPOSllZQQfiChother, an 1 arm positioned onone'of said lugs, sa 1d arm having a jaw,:a-bolt extending loosely through said lugs and:arm,-a jawon one end ofsaid bolt, the bolt being of alength'to bring the j aw thereon into agripping relationship with respect to the other jaw,a'nd a nut inthreading engagement with said'bolt' and engageable with onset said lugsto hold the "jaw on said bolt in the gripping relation with respect tothey other jaw.
